Also known as supply pressure regulator is a device

used to reduce plant air supply to Valve Positioner and

other control equipment. Common reduced air supply

pressures are 20 and 35 psig.

An increase in air pressure to the Actuator is required

Bench Set:

Bonnet:

Bellow seal bonnet:

Extension Bonnet:

The proper definition for bench set is the inherent

Diaphragm pressure range, which are the high and low

values of pressure applied to the diaphragm to produce

rated valve plug travel with atmospheric pressure in the

valve body. This test is often performed on a work

bench in the instrument shop prior to placing the valve

into service and is thus known as Bench Set.

The bonnet or bonnet assembly is that portion of the

valve pressure retaining boundary which may guide the

stem and contains the Packing box and Stem seal. The

bonnet may be integral to the valve body or bolted or

screwed. The bonnet, if it is detachable, will generally

provide the opening to the valve body cavity for

removal and replacement of the internal trim. The

bonnet is generally the means by which the actuator is

connected to the valve body.

A Bonnet which uses a Bellows for sealing against

leakage around the valve plug stem.

A bonnet with a packing box that is extended above the

body to bonnet connection so as to maintain the

temperature of the packing above (cryogenic service)

or below (high-temp service) the temperature of the

process fluid. The length of the extension depends on

the amount of temperature differential that exists

between the process fluid and the packing design

Temperature Related Features:

Selection of the bonnet design is undertaken on the basis of both the operating temperature range and fluid media being

handled. Table 2 below provides a general guide to the temperature limitations of various bonnet designs and packing

materials available.

The Bellows Seal Bonnet option ensures absolute sealing of the process fluid within their rated pressure and temperature

range. An auxiliary packing box in the upper bonnet serves as an emergency seal in the unlikely event of bellows failure. Table

1 shows a general guide when Bellows bonnet is used.

The table 2 below gives a general guide to the limitations of various design features when associated with temperature.

Body:

Booster:

The body of the valve is the main pressure boundary. It provides the pipe connecting ends and the fluid flow passageway. It can

also support the seating surface and the valve Closure Member.

A pneumatic relay that is used to reduce the time lag in pneumatic circuits by reproducing pneumatic signals with high-volume

and or high-pressure output. These units may act as volume boosters or as amplifiers. It can provide the same stroking speed

and can isolate the controller from the large capacitive load of the actuator.

Bubble Tight:

Cavitations:

Choked Flow:

A commonly used term to describe the ability of a control

valve to shut off completely against any pressure on any

fluid. Unfortunately, it is completely unrealistic. Control

valves are tested to ANSI B16.104 which is the American

National Standard for Control Valve Seat Leakage. This

standard uses six different classifications to describe the

valves seat leakage capabilities.

Occurs only in liquid service. In its simplest terms

cavitations is the two-stage process of vaporization and

condensation of a liquid. Vaporization is simply the boiling

of a liquid, which is also known as flashing. In a control

valve this vaporization takes place because the pressure

of the liquid is lowered, instead of the more common

occurrence where the temperature is raised. As fluid

passes through a valve just downstream of the orifice

area, there is an increase in velocity or kinetic energy that

is accompanied by a substantial decrease in pressure or

potential energy. This occurs in an area called the vena

contracta. If the pressure in this area falls below that of the

vapor pressure of the flowing fluid, vaporization (boiling)

occurs. Vapor bubbles then continue downstream where

the velocity of the fluid begins to slow and the pressure in

the fluid recovers. The vapor bubbles then collapse or

implode. Cavitations can cause a Choked Flow condition

to occur and can cause mechanical damage to valves and

piping.

Also known as Critical flow. This condition exists when at a

fixed upstream pressure the flow cannot be further

increased by lowering the downstream pressure. This

condition can occur in gas, steam, or liquid services.

Fluids flow through a valve because of a difference in

pressure between the inlet (Pl) and outlet (P2) of the

valve. This pressure difference (Delta-P) or pressure drop

is essential to move the fluid. Flow is proportional to the

square root of the pressure drop. Which means that the

higher the pressure drop is the more fluid can be moved

through the valve? If the inlet pressure to a valve remains

constant, then the differential pressure can only be

increased by lowering the outlet pressure. For gases and

steam, which are compressible fluids, the maximum

velocity of the fluid through the valve is limited by the

velocity of the propagation of a pressure wave which

travels at the speed of sound in the fluid. If the pressure

drop is sufficiently high, velocity in the flow stream at the

vena contracta will reach the velocity of sound.

Further decrease in the outlet pressure will not be felt

upstream because the pressure wave can only travel at

sonic velocity and the signal will never translate

upstream. Choked Flow can also occur in liquids but only

if the fluid is in a flashing or cavitations condition. The

vapor bubbles block or choke the flow and prevent the

valve from passing more flow by lowering the outlet

pressure to increase the pressure drop. A good rule of

Thumb on Gases and Steam service is that if the

pressure drop across the valve equals or exceeds one

half the absolute inlet pressures, then there is a good

chance for a choked flow condition.

Delta P = 75

Actual pressure drop = 75

Choked Flow is probable.

The movable part of the valve which is positioned in the

flow path to modify the rate of flow through the valve.

Some of the different types of closure members are the

Ball, Disk, Gate, and Plug.

A constant (Cv) that is used to predict the flow rate

through a valve. It is related to the geometry of the valve

at a given valve opening. See Cv for 2 way and 3 way

valves

The relationship between valve travel and the flow rate

through the valve. It is described by means of a curve on

a graph expressed as an installed or inherent

characteristic.

A device which tells a control valve what to do.

Controllers can be either pneumatic or electronic. There

are pressure, temperature, ph, level, differential, and flow

controllers. The job of the controller is to sense one of the

above variables and compare it to a set point that has

been established. The controller then outputs a signal

either pneumatic or electronic to the control valve, which

then responds so as to bring the process variable to the

desired set point.

Diaphragm:

Diaphragm Actuator:

Diaphragm Pressure:

Direct Acting:

Direct Actuator:

Dual Seating:

Dynamic Unbalance:

Effective Area:

A flexible pressure-responsive element that transmits

force to the diaphragm plate and actuator stem.

Is a pressure-operated, spring-opposed diaphragm

assembly which positions the valve stem in response to

an input signal.

See Bench Set.

This term has several different meanings depending upon

the device it is describing. A direct acting actuator is one in

which the actuator stem extends with an increase in

diaphragm pressure. A direct acting valve is one with a

push down to close plug and seat orientation. A direct

acting positioner or a direct acting controller outputs an

increase in signal in response to an increase in set point.

Is one in which the actuator stem extends with an increase

in diaphragm pressure.

A valve is said to have dual seating when it uses a resilient

or composition material such as TFE or Buna-N, etc. for

its primary seal and a metal-to-metal seat as a secondary

seal. The idea is that the primary seal will provide tight

shut-off Class VI and if it is damaged the secondary seal

will backup the primary seal with Class IV shut-off.

The total force produced on the valve plug in any stated

open position by the fluid pressure acting upon it. The

particular style of valve, i.e. single-ported, double-ported,

flow-to-open, flow-to-close, has an effect on the amount of

dynamic unbalance.

For a Diaphragm actuator, the effective area is that part of

the diaphragm area that is effective in producing a stem

force. Usually the effective area will change as the valve is

stroked - being at a maximum at the start and at a

minimum at the end of the travel range. Flat sheet

diaphragms are most affected by this; while molded

diaphragms will improve the actuator performance, and a

rolling diaphragm will provide a constant stem force

throughout the entire stroke of the valve.

Feedback Signal:

Flashing:

The configuration provided to make a pressure-tight joint

to the pipe carrying the fluid to be controlled. The most

common of these connections are threaded, flanged, or

welded.

Is the distance between the face of the inlet opening and

the face of the outlet opening of a valve or fitting. These

dimensions are governed by ANSI/ISA specifications.

Or normally closed. Another way of describing an AIR-

TO-OPEN actuator. Approximately 80% of all spring

return diaphragm operators in the field are of this

construction.

In case of Electrical actuator - stay put type

A term used to describe the ability of an actuator to stay at

the same percent of travel it was in when it lost its air

supply. On spring return Actuators this is accomplished

by means of a lock up valve. On Piston Actuators a series

of compressed air cylinders must be employed.

Or normally open. Another way of describing an AIR-TO-

CLOSE actuator.

A term used to describe the desired failure position of a

control valve. It could fail closed, fail open or fail in place.

For a spring-return operator to fail-in-place usually

requires the use of a lock-up valve.

The return signal that results from a measurement of the

directly controlled variable. An example would be where

a control valve is equipped with a positioner. The return

signal is usually a mechanical indication of valve plug

stem position which is fed back into the positioner.

Is the boiling or vaporizing of a liquid. See the definition of

cavitations. When the vapor pressure downstream of a

control valve is less than the upstream vapor pressure,

part of the liquid changes to a vapor and remains as a

vapor unless the downstream pressure recovers

significantly, in which case cavitations occurs. Flashing

will normally cause a choked flow condition to occur. In

addition the vapor bubbles can also cause mechanical

damage to the valve and piping system.

Gain:

Hand wheel:

Hysteresis:

Example:

Installed Diaphragm Pressure:

Example:

The relationship of input to output. If the full range of the

input is equal to the full range of the output, then the gain is

1. Gain is another way to describe the sensitivity of a

device.

A manual override device used to stroke a valve or limit its

travel. The hand wheel is sometimes referred to as a hand

jack. It may be top mounted, side mounted, in-yoke

mounted or shaft mounted and de-clutch able.

The difference between up-scale and down-scale results

in instrument response when subjected to the same input

approached from the opposite direction.

A control valve has a stroke of 1.0 inch and we give the

valve a 9 psig signal. The valve travels 0.500 of an inch.

We then give the valve a 12 psig signal, and the valve

travels to 0.750 of an inch. When the valve is then given a

9 psig signal, the stroke is measured at 0.501. That

represents hysteresis.

Hysteresis can be caused by a multitude of variables,

packing friction, loose linkage, pressure drop, etc.

There are simply too many variables in the valve and the

system to answer the question properly. The control valve

only responds to the controller signal and will move to a

position to satisfy the controller - thus negating the effects

of hysteresis.

The high and low values of pressure applied to the

diaphragm to produce rated travel with stated conditions

in the valve body. The "stated conditions" referred to here

mean the actual pressure drops at operating conditions.

A control valve may have an inherent

Diaphragm pressure or Bench set of 8 to 15 psig. But

when subjected to a 600 psig inlet pressure, it may start to

open at 3 psig. and be full open at 15 psig. It is because of

the forces acting on the valve plug and the direction of flow

through the valve (FLOW-TO-OPEN or FLOW-TO-

CLOSE) that the installed diaphragm pressure will differ

from the inherent diaphragm pressure.

Instrument Pressure:

Integral Seat:

I/P:

Lantern Ring:

Lapped-In:

Leakage Classification:

Leak-Off:

The output pressure from an automatic controller that is

used to operate a control valve. It is the input signal to the

valve.

The flow control orifice and seat that is an integral part of

the valve body or cage. The seat is machined directly out

of the valve body and is normally not replaceable without

replacing the body itself - although some can be repaired

by welding and re-machining

An abbreviation for current-to-pneumatic signal

conversion. This term is commonly used to describe a

type of transducer that converts an electric (4-20 mA)

input signal to a pneumatic (3-15 psig.) output signal.

A rigid spacer used in the packing with packing above

and below it. The lantern ring is used to allow lubrication

to the packing or allow access to a leak off connection. On

some of the new fugitive emission packing systems, it

also acts as a stem guide.

A term that describes a procedure for reducing the

leakage rate on metal-to-metal seated valves and

regulators. The plug and seat are lapped together with

the aid of an abrasive compound in an effort to establish a

better seating surface than would normally be achieved

by means of machining.

A term used to describe certain standardized testing

procedures for control valves with a Flow coefficient

greater then 0.1 (Cv). These procedures are outlined in

ANSI Standard, which gives specific tests and tolerances

for six seat leakage classifications. It should be

remembered that these tests are used to establish

uniform acceptance standards for manufacturing quality

and are not meant to be used to estimate leakage under

actual working conditions.

A term used to describe a threaded connection located

on the bonnet of a valve that allows for the detection of

leakage of the process fluid past the packing area.

Piston Actuator:

Plug:

A special type of regulator that is installed between the

valve positioner and the valve actuator, where it senses

the supply air pressure. If that pressure falls below a

certain level, it locks or traps the air loaded into the

actuator causing the valve to fail in place.

A valve design that dissipates a considerable amount of

flow stream energy due to turbulence created by the

contours of the flow path. Consequently, pressure

downstream of the valve vena contracta recovers to a

lesser percentage of its inlet value than a valve with a

more streamlined flow path.

Is used to designate Inlet Pressure.

Is used to designate Outlet Pressure.

A sealing system that normally consists of a deformable

material such as Teflon, graphite, asbestos, etc. It is

usually in the form of solid or split rings contained in a

packing box that are compressed so as to provide an

effective pressure seal.

The chamber located in the Bonnet which surrounds the

stem and contains the packing and other stem-sealing

components.

A part that transfers a mechanical load to the packing from

the packing flange or nut.

A fluid-powered, normally pneumatic device in which the

fluid acts upon a movable cylindrical member, the piston,

to provide linear motion to the actuator stem. These units

are spring or air opposed and operate at higher supply

pressures than a spring return Diaphragm actuator.

Port-Guided: A valve plug that fits inside the seat ring,

which acts as a guide bushing. Examples: Splined Plug,

Hollow Skirt, and the Feather-Guide Plug.

Position Switch:

Position Transmitter:

Positioner

A switch that is linked to the valve stem to detect a single,

preset valve stem position. Example: Full open or full

closed. The switch may be pneumatic, hydraulic or

electric.

A device that is mechanically connected to the valve stem

and will generate and transmit either a pneumatic or

electric signal that represents the valve stem position.

A device used to position a valve with regard to a signal.

The positioner compares the input signal with a

mechanical feed back link from the actuator. It then

produces the force necessary to move the actuator

output until the mechanical output position feedback

corresponds with the pneumatic signal value. Positioners

can also be used to modify the action of the valve

(reverse acting positioner), alter the stroke or controller

input signal (split range positioner), increase the

pressure to the valve actuator (amplifying positioner), or

alter the control valve flow characteristic (characterized

positioner). Refer Figure 1

Push-down-to-Close :

A term used to describe a linear or globe style valve

that uses a direct acting plug and stem

arrangement. The plug is located above the seat

ring. When the plug is pushed down, the plug

contacts the seat, and the valve closes.

Soft Seated:

Split Body:

Static Unbalance:

Stellite:

Stem:

Stem Guide:

Supply Pressure:

A term used to describe valve trim with an elastomeric or

plastic material used either in the valve plug or seat ring to

provide tight shutoff with a minimal amount of actuator

force. A soft seated valve will usually provide class VI seat

leakage capability.

A valve whose body is split. This design allows for easy

plug and seat removal. Split-bodied valves are made in

both the straight-through and angle versions.

The net force produced on the valve stem by the fluid

pressure acting on the closure member and stem within

the pressure retaining boundary. The closure member is

at a stated opening with a stated flow condition. This is

one of the forces an actuator must overcome.

Also called #6 Stellite or Alloy 6. A material used in valve

trim known for its hardness, wear and corrosion

resistance. Stellite is available as a casting, bar stock

material and may be applied to a softer material such as

316 stainless steel by means of spray coating or welding.

The valve plug stem is a rod extending through the bonnet

assembly to permit positioning of the plug or closure

member. The actuator stem is a rod or shaft which

connects to the valve stem and transmits motion or force

from the actuator to the valve.

A guide bushing closely fitted to the valve stem and

aligned with the seat. Good stem guiding is essential to

minimizing packing leakage.

The pressure at the supply port of a device such as a

controller, positioner, or transducer. Common values of

control valve supply pressures are 20 psig. for a 3-15

psig. output and 35 psig. for a 6-30 psig. output.

Transducer: An element or device which receives

information in the form of one quantity and coverts it to

information in the form of the same or another quantity.

(See I/P)

Turndown:

Range ability:

Reverse Acting:

Seat Load:

Seat Ring:

Travel:

A term used to describe the ratio between the minimum and

maximum flow conditions seen in a particular system.

Example: If the minimum flow were 10 G.P.M. and the

maximum flow were 100 G.P.M. the turndown would be

10:1. This term is sometimes incorrectly applied to valves.

See range ability.

The range over which a control valve can control. It is the

ratio of the maximum to minimum controllable flow

coefficients. This is also called turndown although

technically it is not the same thing. There are two types of

range ability - inherent and installed. Inherent range ability is

a property of the valve alone and may be defined as the

range of flow coefficients between which the gain of the

valve does not deviate from a specified gain by some stated

tolerance limit. Installed range ability is the range within

which the deviation from a desired installed flow

characteristic does not exceed some stated tolerance limit.

This term has several deferent meanings depending upon

the device it is describing. A reverse-acting actuator is one in

which the actuator stem retracts with an increase in

diaphragm pressure. A reverse-acting valve is one with a

push-down-to-open plug and seat orientation. A reverse-

acting positioner or a reverse-acting controller outputs a

decrease in signal in response to an increase in set point.

The contact force between the seat and the valve plug.

When an actuator is selected for a given control valve, it

must be able to generate enough force to overcome static,

stem, and dynamic unbalance with an allowance made for

seat load.

A part of the flow passageway that is used in conjunction

with the closure member to modify the rate of flow through

the valve.

The distance the plug or stem moves in order to go from a

full-closed to a full-open position, also called stroke.

Trim: Includes all the parts that are in flowing contact with the

process fluid except the body, bonnet, and body flanges and

gaskets. The plug, seats, stem, guides, bushings, and cage

are some of the parts included in the term trim.


Reduced Trim:

Balanced Trim:

Anti-Cavitations Trim:

Cage:

Cage Guided Valve:

Flow Characteristic:

Is an undersized orifice. Reduced or restricted capacity

trim is used for several reasons. (1) It adapts a valve large

enough to handle increased future flow requirement with

trim capacity properly sized for present needs. (2) A valve

with adequate structural strength can be selected and still

retain reasonable travel vs. capacity relationships. (3) A

valve with a large body using restricted trim can be used to

reduce inlet and outlet fluid velocities. (4) It can eliminate

the need for pipe reducers. (5) Errors in over sizing can be

corrected by use of restricted capacity trim.

A trim arrangement that tends to equalize the pressure

above and below the valve plug to minimize the net static

and dynamic fluid flow forces acting along the axis of the

stem of a Globe valve.

A special trim used in control valves to stage the pressure

drop through the valve, which will either prevent the

cavitations from occurring or direct the bubbles that are

formed to the center of the flow stream away from the

valve body and trim. This is usually accomplished by

causing the fluid to travel along a torturous path or through

successively smaller orifices or a combination of both.

A hollow cylindrical trim element that is sometimes used

as a guide to align the movement of a valve plug with a

seat ring. It may also act to retain the seat ring in the valve

body. On some types of valves, the cage may contain

different shaped openings which act to characterize the

flow through the valve. The cage may also act as a noise

attenuation or anti cavitations device.

A type of Globe style valve trim where the valve plugs with

the seat.

The relationship between valve capacity and valve travel.

It is usually expressed graphically in the form of a curve.

Control valves have two types of characteristics inherent

and installed. The inherent characteristic is derived from

testing the valve with water as the fluid and a constant

pressure drop across the valve. When valves are

installed into a system with pumps, pipes, and fittings, the

pressure dropped across the valve will vary with the

travel. When the actual flow in a system is plotted against

valve opening, the curve is known as the installed flow

characteristic. Valves can be characterized by shaping

the plugs, orifices, or cages to produce a particular curve.

Valves are characterized in order to try to alter the valve

gain.

Valve gain is the flow change divided by the control signal

change. This is done in an effort to compensate for

non-linearity in the control loop.

It is the relationship between valve capacity and valve

travel and is usually expressed graphically. It is derived

from testing a valve with water as the fluid and with a

constant pressure drop across the valve. The most

common types of inherent flow characteristics are Linear,

Equal percentage, modified parabolic and quick

opening.

The flow characteristic when the pressure drop across

the valve varies with flow and related conditions in the

system in which the valve is installed. The purpose of

characterizing a control valve is to help compensate for

non-linearities in the control loop.

A term used to describe a type of valve flow characteristic

where for equal increments of valve plug travel the

change in flow rate with respect to travel may be

expressed as a constant percent of the flow rate at the

time of the change. The change in flow rate observed with

respect to travel will be relatively small when the valve

plug is near its seat and relatively high when the valve

plug is nearly wide open, in case of linear the flow is

directly proportional to the lift and finally on/off either the

flow is fully on or fully closed.

A flow characteristic that lies somewhere between Linear

and Equal percentage. It provides fine throttling at low

flow capacity and an approximately linear characteristic

at higher flow capacities

SUDESUDE


Equal Percentage Characteristic:

We recommend that the trim be chosen that would be between 75 and 85 percent open at maximum flow conditions. However,

should the trim size be selected on the normal flow conditions only then we recommend a trim be chosen that would

be between 65 and 75 percent open.

If minimum flow condition is specified the selected trim should be checked with regard to being suitable to control

this condition.

High Friction (Solid only), Refer Table 3

Where trim sizes are designated in inches this nominal size reference and does not signify any actual dimensions

of the trim. In some case it may have a very approximate relationship to the seat bore this should never be assumed for

calculation purposes. (Refer Figure 4)

Linear Characteristic:

We recommend that a trim be chosen which would be between 85 and 95 percent open at the maximum flow conditions,

although the valve would control upto 100 percent open. This margin at the upper end allows for any contingency. However,

should the trim size be selected on the normal flow conditions only then we recommend that a trim be chosen that would be

between 75 and 85 percent open.

In short whenever we sized the valve even the climatic condition is also to be considered therefore the sizing is required to be

considered at lift between 80 to 85 percent, the balance lift kept as a buffer for the climatic condition which will affect the flow

characteristics. If a minimum flow condition is specified the selected trim should be checked with regard to being suitable to

control this condition. Never have a modulating valve operating on minimum flow conditions below the maximum range ability

levels stated as there will be a little or no control. If the flow condition can not be handled then two valves operating in parallel

should be considered working on split range signal.

The pressure drop across the trim is split between the contoured nose and the clamped in

characterized guide. Flow direction is under the plug, which incorporates a number of steps to help

offset cavitations effects at low valve lifts.

For arduous duty with extremely high pressure drops a protection sieve may be included around the

trim guide. (Refer figure 4)

SUDESUDE

The inherent flow characteristic of a control valve is the relationship between the flow and the valve travel at constant

pressure drop. As with all caged multi hole trims the actual characteristic may vary slightly from the true curve

Definitions:wLinear

Flow is directly proportional to valve lift.

wEqual %

Flow changes by a constant percentage of its

instantaneous value for each unit of Valve lift.

wQuick Opening

Flow increases rapidly with initial travel

reaching near its maximum at a low lift.

Standard Duty

The Contoured and Ported cage design are the standard

trim option available, being suitable for modulating or on/off

applications, satisfying a large percentage of process

requirements.
